[menu-bar] Can't focus component after opening sub-menu

[jouni]

Description

When first rendered, a menu-bar can be focused with the tab key as expected. Once you open and close a sub-menu and move focus away from the menu-bar, you can no longer focus it with the keyboard.

Expected outcome

Component is always focusable with the tab key (unless it’s disabled).

Minimal reproducible example

Use the dev/menu-bar.html page to test:

Steps to reproduce

• Open /dev/menu-bar.html
• Press tab → View is focused
• Press Enter → Sub-menu opens, Ruler is focused
• Press Enter → Sub-menu closes, View is focused again
• Press Tab → Focus moves to the browser chrome
• Press Tab multiple times → Focus should move to the menu-bar, but instead keeps moving between the browser chrome and the web page.

Environment

Tested on Chrome, Firefox, and Safari on macOS.

Confirmed. This is a regression in V25, the problem is not reproducible on 24.9 branch.
